FOSSiBOT FAC580 DC-DC Battery Charger | 580W
- Due to voltage limitations on the solar input port, which vary by model, the maximum PV input is 200W for the F1200/F800 and 500W for the F2400, neither of which reaches the theoretical maximum of 580W.
- 580W Battery Charger, 6× faster than traditional in-vehicle auxiliary power outlets.
- Works with all FOSSiBOOT models and compatible with third-party portable power stations.
- Suitable for a variety of vehicles, including SUVs, pickups, and RVs.
- 6-step easy installation
- 2 years worry-free warranty (automatically applied if purchased from our official website)

FAQ
A: A traditional 12V cigarette lighter port provides a maximum output of 100W (200W for 24V systems), while the F580 delivers up to 580W of output power — 6 times faster vehicle charging.
A: Suitable for all fuel-powered vehicles equipped with 12V/24V starter batteries, including:
• RVs / Campervans
• Commercial vans
• Trucks and construction vehicles
A: Compatible with hybrid vehicles (must have an alternator and starter battery).
Not compatible with pure electric vehicles due to different power system architectures.
A: The FAC580 automatically shuts off when the battery voltage drops below 12.5V (or 12V), preventing battery drain. No manual shutdown is required.
A: The dual-voltage mode (12.0V / 12.5V) helps protect the battery. With proper use, it won’t cause measurable lifespan reduction.
A: The impact is negligible — it uses the alternator’s surplus power (<0.5L/100km under typical conditions).
• Make sure the vehicle is turned off before installation.
• Perform a test fit to confirm functionality before final installation.
• Operate only one terminal (positive or negative) at a time to avoid short circuits or shock.
• Wear protective gear such as gloves and safety goggles.
• Professional installation is recommended for optimal safety.
• Required: Wrench (for battery terminal bolts)
• Optional: Drill + wooden board (if installing in the trunk)
• Included: Hex screwdriver (for cable connection)
• Note: Leave at least 10cm of clearance for cooling airflow.
A: Installation position is flexible — just ensure proper ventilation for the cooling fan.
A: Yes.Simple installation with detailed instructional videos provided.
The most complex step (routing cable from engine bay to trunk) is demonstrated step-by-step.
A: The standard package includes a 5-meter 6AWG cable. Using the original cable is recommended.
If using your own, ensure cable reliability and proper gauge.
After stopping the vehicle, check the following:
• Are positive and negative connections correct?
• Are cable terminals firmly secured?
• Restart the engine and observe the indicator light.
• Keep the engine running to charge the car battery.
• If the issue persists, contact technical support.
A: Compatible with all FOSSiBOT models and third-party devices that feature MC4 solar input ports (charging rate may vary).
Ensure the third-party device supports up to 50V input voltage.
Please check:
• Your power station supports 580W DC input.
• The FAC580 is well-ventilated and operating below 40°C.
• 12V vehicles: ≤45A
• 24V vehicles: ≤22.5A
Cigarette lighter output: approx. 100W
FAC580 stable output: 580W (lab-tested)
A: For most models, use the solar input port:
• F800 & F1200: XT60 input portF2400 &
• F3600 Pro: XT90 input port
